Australian researchers have determined in a pig study that a swallowable gas sensor capsule might be a useful tool in accurately diagnosing gastrointestinal problems. Using the sensor capsule, the researchers were able to detect the effect of cinnamon and heat-stress on the various gases produced in the gut during digestion. They found, for example, that consuming cinnamon cools the body a couple of degrees and improves overall health. Under normal feeding conditions at room temperature, CO2 gas increases in the stomach, but decreases in the presence of cinnamon. The researchers concluded the capsule could be “a highly reliable device for monitoring/diagnostics of gastrointestinal disorders.”
